Welcome to LGM, lorgo.
I would search
www.Sheetmusicplus.com for Praise+Worship sheet music and fakebooks, like Integrity, Vineyard and the WOW series. They would have some songs in minor keys - Am, Em, Dm are popular Guitar keys. If you read TAB, search for books in that format. These are mostly CCM. Many Hebrew-flavored songs are minor, like KING OF KINGS and many by Paul Wilbur.
Many Gospel songs tend to be in FLAT keys like Db, Ab, Eb, etc. Very unfriendly for the beginning Guitar. You can put Capo on the 1st fret and play in the next key down, like chords in G for a song in Ab. And since Gospel is heavily influenced by the Blues, you'll find that major/minor ambiguity with the Blue notes, so they are really in between Major and Minor.
Some Spirituals and Classic Gospel songs in minor keys -
Go Down Moses
Wade In The Water
Keep Your hand on the Plow
Lord, Don't Move that Mountain
A more current minor Gospel chorus is LION OF JUDAH (Em) - I think that's done by Eddie Long -
